per litre
Official composition (mg/L): sodium 9.25, calcium 15.6, potassium 1.59, magnesium 7.8, chloride 6, sulphate 3. Bicarbonate is printed as 1.06 mg/L, which cannot balance the cations and is probably a misprint, so it is kept in the research file only. No pH or TDS published, so it is not scored.
